Understand this story
Spanish optical lens company IOT has developed Light-Form additive manufacturing technology, which forms progressive multifocal lenses in a single step through stabilized frontal photopolymerization; lens formation takes only a few seconds, and the first commercial products have already entered the consumer market. The technology supports resin recycling, eliminates cutting and polishing steps and manufacturing water use, and there are plans to explore multi-printhead equipment and in-store customized production. IOT also plans to extend the technology to smart glasses and AR/VR devices, exploring direct printing of vision-correction optical structures on optical waveguides or flat substrates, but related applications remain a direction of technology development.

IOT launches Light-Form technology; future vision-correction optical structures may be printed directly onto AR optical waveguides
Spanish optical lens company IOT has launched Light-Form additive manufacturing technology, which forms progressive multifocal lenses in a single step through stabilized frontal photopolymerization. Lens formation takes only seconds, and the first batch of commercial products has already entered the consumer market. The technology supports resin recycling, eliminates cutting and polishing processes and manufacturing water use, and the company plans to explore multi-printhead equipment and in-store customized production. IOT also plans to extend the technology to smart glasses and AR/VR devices, exploring the direct printing of vision-correction optical structures onto optical waveguides or flat substrates, but related applications remain a direction of technology development.
